  • Aurora unlikely. Tonight's forecast peaks at Kp 2.0. From here you'd usually need about Kp 5.
  • Space station passes at 5:39 AM, up to 33° high, moving SW → E. It looks like a bright, steady star that crosses the sky in a few minutes.
  • Moon 35% lit (Waxing Crescent), above the horizon for 27% of the dark hours.
  • Clouds: about 0% effective cover during dark hours, so mostly clear.
